Chapter 450: Refining the Demon Core!_1

"Warden, the Spiritual Power within the Demon Core is too wild and rampageous, and human cultivators wish to absorb it must refine away the impurities. But as long as one is not greedy, there won't be any danger,"

the old man hurriedly explained, fearing Zhou Yuan's questions, "I have plenty of these. If ever you cannot refine the impurities, do not fear wasting them, you must stop in time."

While he explained, Zhou Yuan perused the Great Zhou Secret Technique once more, confirming there was no deception before saying, "Thank you, Senior!"

He was so insanely driven to enhance his strength that he promptly took the Fourth Grade Demon Elixir and hurried to his room to begin its refinement.

And when the Dantian was opened, the Spiritual Power from the Demon Core was continuously absorbed.
